Today is a piece of news that I saw on Xinhua News Agency, and I would like to share it with you. This message is very long, so I'll go through it briefly.
There was something like a flying carpet, and the boxy silver metal plate stood out. According to the staff, this model is a scaled-down prototype of a new generation of communication satellites developed by Galaxy Airlines and the main products such as phased array antennas, which can be used to support high-end communication technologies such as mobile direct access satellites. This new generation of communication satellite, in a space of a few square meters, integrates communication antennas, and solar panels that convert solar energy into satellite energy, is a communication satellite integrating phased array and solar wings. ”
According to Zhang Shijie, chief scientist of Galaxy Aerospace, this technology is called 'wing array combination', our R&D team has carried out two-dimensional key technology research on the satellite, and then we will also conduct in-depth research on key technologies such as wing array integration, efficient heat dissipation, distributed power supply, etc., by hiding the antenna in the solar wing, the volume and cost of the satellite can be greatly reduced, and the network efficiency when deploying multiple satellites can be improved. ”
The title of this article is "China is carrying out the development of a new generation of communication satellites", and from this article, we can summarize three key technologies.
The first is a communication satellite that can be directly connected to the mobile **, that is, there is no need to install antennas and the like.
The second point, which is its shape, becomes a "flying carpet" instead of boxy, with two huge ears. This "flying carpet" has a solar panel mounted on the front and a phased array antenna on the back. On the one hand, this kind of flake satellite can increase the power supply capacity by adding solar panels, and on the other hand, it can also use solar panels in a large area and arrange a large number of phased array antennas in the other direction, so as to improve the signal quality to the ground, so that the mobile phone can be directly connected to the satellite.
Moreover, this kind of satellite can also be folded, a satellite as thin as a cicada's wing, which can hold more satellites.
In the past few years, everyone has been talking about the "Starlink" of the United States, as if "Starlink" is the world's most cutting-edge satellite communication technology. The most advanced part of "Starlink" is to transfer the ground stations on the earth to space, instead of building thousands of ground stations on the earth like on the earth, thus saving a lot of manpower and material resources.
At the same time, because the setting of ground ground stations will be constrained by many factors, it is difficult to achieve worldwide interconnection, and the migration of ground stations to satellites can easily connect the world at a low cost, which is the real breakthrough of "Starlink" technology.
After seeing the American "Starlink", many people sighed with emotion, I don't know when we can also have China's "Starlink". And it must be a technology that surpasses the American "Starlink".
From this article by Xinhua News Agency, you can probably understand the advanced points of China's "Starlink", and most importantly, it has achieved direct connection with satellites, which is much better than the American "Starlink", and its unique shape and folds have greatly reduced its launch cost.
For a long time, people have been concerned about the extent to which China's "Starlink" has developed, and this news from Xinhua tells us that this technology can already be sent through Xinhua News Agency, which indicates that this day will come soon.
